The .inlet head 2, at one end of the handle, conducting the mixed'gasesfrom thenniiic.-fl is provided-with 'an oxygen passag way 10 ing bead M to the discharge. assiigeivansr an tvlen. fissa ewa 11. desi -A between the inner tube 132 an i an ace i P g Y g mat'portions'bftbe 110 inner-tube areseparated from the outer tube as shown in FigsII and III to produce the dischar e passageways-just referred to.

The ifferent gases passing from the ducts and '27 in the mixing head M, flow 4througha primary mixing device P from 4which, they are discharged into a secondary.

mixing chamber S (Fig. I) communicating with the passageway 34. The primary mixing device is screwed 'into the mixing head 'M and its` reduced inner-end engages the mixing head as shown in Fig. I. An annui lar acetylene chamber is formed around ',rality.l of restrlcted inlet ports 38 and 39.

'I he restricted inlet ports 38, communicat. ing with the oxygen chamber 36, are sut stantially equal in diameter to the restricted inlet ports 39 which communicate with the acetylene chamber 35, and these different inlet ports 38 and 39 are smaller in diameter than the primary mixing chambers 37.

One of the objects in forming a plurality of primary mixing chambers in the primary mixing device is to Aprevent a backfire or whistling of thel combustible gases, and

this object is attained by making the primary mixing chambers so small that the flame'will not travel backwardly through the restricted passageways formed by these .mixing chambers. Since the primary mixing chambersfarevery small in diameter it is necessary, or'de'sirabl'e, to provide a plurality of such chambers, so that the desired volume of gases may be forced through the 'mixing head under the ordinary degree of pressure. If only one restricted primary mixing chamber was formed in the mixing device, it would be necessary to maintain the gases under an extremely high 'degree of pressure to secure the required volume or rate ofyflow of gases at the tip.

Another advantage, gained by'forcin-g the other, and thereafter discharging the vdifferent gases through a plurality of primary mixing chambers, is that a thorough mixture is insured bymixin'g the gases in thedi'e'rent restricted chambers where the fine streams of gases are mingled with each ases .into a secondary mixing chamber lS Fig. I) where the different streams of Vgases are mixed with each other. vA further advantage is obtained by forming the inlet ports 39 tangentially with respect to primarymixingchambers 37 (Fi .'IV) so that the acetylene gas, discharge from saidl tangential inlet ports, lwill whirl., around in the pri` mary mixing chambers-,thel eby insuring a' thorough mixture of the' ierent ases. Another desirable feature `of then mixing point beyond the smoot deviceis that the different streamsv ofz gases passing from the primary mixing chambers, are thoroughly mixed 'm the secondary mixingl chamber S. In this connection, it Will be noted that the pririary mixing chambers 37 are formed at an angle to each other and at an angle to the axis of the mixing device P, said mixing chambers being separated4 from each other a greater distance at their inlet ends than at their discharge ends, see Figs. I and IV. By arranging the mixing chambers 37 in this manner, the stream of gases passing from each of themis discharged into a stream of gases passing from another of said mixing chambers, and furthermore the different gases discharged at an angle to the axis of the mixing device P,

are whirled around the conical bottom wall of the .primary mixing chamber S.

The double tip T is constructed to receive an additional supply of oxygen gas which passes through an auxiliary passageway 45 in the coupling member 30 and which is disi charged through "the inner tip member 32. A ring 46, surrounding the coupling mem ber 30, at the inlet end of passageway y45, is provided with an inlet port 47 which communicates with an annular passageway 48 formed around the coupling member 30. The ringi. 46 lies between the enlarged portion 31 of coupling member 30 and the bottom face of the mixing head M,said ring being detachably secured to the Vmixing head by means of the coupling 30. 49 designates an auxiliary oxygen supply pipe secured to the ring 46 and leading from the inlet port 47 in said ring to the oxygen valve O. The valve O is provided with apassageway 50 thro/ugh which oxygen is conducted tov an annular passageway 51 formed in a ring 52 sageway 51. 54' designates a needle valvefor controllingV the How ,ofoxygenifrom the pipe 49.

The coupling head 8 (Fig. I) is provided with a smooth seat which engages the mixing head M, and the union coupling mem'- ioo ber-9 is utilized tojpro-tect thissmooth seat v tached fromithe mixing ahead.'v The vscrew V fromlinjury when the couplinghead is defor limiting the movement of said ,union coupling member. It will be noted` thatthe inturnedflange 57- of the union coupling lies between the stop member 56 and the out' turned `flange 58 of the coupling head'8, vso

lthat the union couplingl cannot' move to la plieghed v which surrounds the discharge end of pasy In Fig. V we have shown the primary finixin ldevice P applied directlyto the coupling i ead 8', and the-tip`r T is coupled to the" head 8 by means of the union Icoupling 9.A i J To prevent the tips from melting under the excessive heat of the Oxy-acetylene flame, they are usually made of copper or other expensive material adapted to withstand `such heat.` The nozzle sections 32 and 33 shown in Fig. I aswell as the nozzle section 59' shown in Fig. V are preferably made-,of cop'per, and to reducefthe cost of the tips the nozzle sections are preferably provided with. heads madeof some other material. 60 designates a head section screwed onto the nozzle ,section 59, an end of said nozzle sec-V tion fbeing-upset and sunk yinto the head section 160. f The diiferent sections 59 and 60 areilthuspermanently secured together to form an inexpensive tip-having a `nozzle sectionf"made of copper, and a head section infade of comparatively inexpensive material.
